You probably associate Black Friday with deals on TVs, games consoles and gadgets.
But fashion brands, too, are getting in on the act with big discounts top-to-bottom on everything from hats to shoes.
New Look has already kicked off with discounts of up to 40%, although these are currently only available online. Offers include a white faux fur hooded biker jacket down from £49.99 to £29.99 and several styles of this year's over-the-knee boots with prices as low as £26.99.
Tobi, too, is already giving customer 50% off site-wide with the code ALL50.
Topshop hasn't yet released its deals, but is promising free delivery on all orders on Topshop.com from 24th-28th November. River Island is also keeping quiet so far about its Black Friday deals, but says it will have plenty of offers on fashion, accessories, beauty and more.
Meanwhile, Lola Rose will have a set page dedicated to Black Friday deals, offering 50% off most of its jewellery; and bridal and occasion shoe brand, Elegant Steps, will be offering 20% off everything across the site.
Karen Millen is starting a day early, on Thursday, with offers running until next Monday; there's 25% off everything, with bigger discounts on selected items.
Online retailer ASOS is already offering discounts of up to 70%, and Matalan has 50% off items across its range for the next eight days.
Miss Selfridge is promising 50% off jeans, trousers and skirts, with free delivery.
And Very has already started its Black Friday sale, which will last until next Tuesday. It has big discounts across the range, including half price offers on both fashion and footwear.
But not every fashion store is taking part. Fat Face, for example, has said it plans to give over £100,000 to charity, instead of cutting prices. Next, too, says it won't be having a special Black Friday sale.
